    Solar Overtakes Coal in US for First Time

    Key Takeaway

    – Scientific consensus confirms human activity, especially fossil fuels, is the primary driver of modern climate change.
    – Continued “business as usual” will have overwhelmingly negative consequences for society and the environment.
    – Solar energy overtook coal in US electricity generation for the first time in May 2026.
    – Solar’s share more than doubled in five years, while coal’s share nearly halved.
    – Renewable energy records are growing despite a divided political climate and counterproductive policies.

    Climate Views and the Scientific Truth

    Peoples opinions on climate change typicaly splits into five groups, as seen in statements like that. No matter which one fits your thinking, the scientific community agrees our planet is warming and its manly because of human actions, like burning fossil fuels, cutting down forest, and other greenhouse gas releases—these are the main drivers of the dramatic shifts we’ve seen since the mid-1900s. More crucially, experts warn that if we stick with a “business as usual” approach, itll bring lots of bad outcomes for both societys and the environment in general.

    Renewable Energy’s Critical Role

    Switching to renewable power is absolutely necessary for fighting climate change caused by people, given that fossil fuels still supply 80% of global energy. In this context, solar energy in the US surpassed coal production for the first time ever in May 2026, delivering 12.8% of electricity compared to coal’s 12.2%.

    • Coal’s share in the US electricity mix fell from 19.7% in May 2021 to 12.2% in May 2026, almost halving.
    • Solar’s contribution more than doubled in the same timeframe, rising from 5.4% to 12.8%.
    • This marks a big change in the US energy landscape over the last five years.

    Milestones and Future Implications

    These events happened after another clean energy highlight in March, when renewables togeather outpaced natural gas for the first time nationwide. Overal, the new records point to the growing presence of renewable energy across the United States, even though the political scene remains split and some policies actually work against climate sustainability efforts. Its a mixed picture of progress and hurdles.

    • Wind Droughts: A New Challenge for Energy Transition and Supply Stability

      Wind Droughts: A New Challenge for Energy Transition and Supply Stability

      Key Takeaways

      1. Wind energy has grown significantly but faces challenges from increasing occurrences of wind droughts, which hinder electricity generation.
      2. Wind droughts are expected to become more frequent and prolonged globally, particularly affecting countries that rely heavily on wind energy, like the UK, Germany, and Denmark.
      3. Atmospheric changes, including decreased mid-latitude cyclone frequencies and Arctic warming, are influencing wind patterns and contributing to wind droughts.
      4. Dunkelflaute events, when both wind and solar energy production are low, have led to significant price spikes in energy markets, highlighting vulnerabilities in renewable energy supply.
      5. To address supply risks, it is essential to enhance grid resilience, diversify energy sources, and ensure adequate dispatchable capacity and storage solutions.

      The decrease in prices and the necessity to fulfill worldwide obligations towards net zero have fueled the development of renewable energy sources, including solar PV, wind farms, geothermal, and even hydroelectric power. Each type of technology comes with its own unique challenges, and wind energy is no exception: wind droughts pose a risk to both the dependability and pricing of generated electricity.

      Wind Energy Growth

      Wind energy has experienced an increase in installed capacity, providing a more stable supply than options like solar power. Nevertheless, in recent years, wind droughts have emerged as a new concern that must be addressed.

      Understanding Wind Droughts

      Similar to traditional droughts, a wind drought is an extended duration with low wind speeds that hinder electricity generation. This is particularly difficult for nations that heavily depend on wind energy, like the UK, Germany, and Denmark, but this pattern appears to be a global issue.

      A recent research article, published in July 2025 in Nature Climate Change, suggests that wind droughts are on the rise after examining hourly data. The findings indicate that, both globally and regionally, wind droughts will become more frequent and prolonged across various scenarios. The length of these events is expected to increase by up to 20% under low warming conditions and 40% by the year 2100 in northern mid-latitude countries. This poses a risk to energy security in these densely populated regions, as stated in the report.

      Atmospheric Changes

      “The trends are mainly driven by falling mid-latitude cyclone frequencies and warming in the Arctic,” the report concludes. These atmospheric changes impact specific areas more than others, but their consequences can be observed worldwide.

      The International Energy Agency (IEA) has raised concerns about “Dunkelflaute” events, periods when both wind and solar energy production are significantly low, affecting supply and energy prices. During such times, thick cloud cover diminishes solar radiation in certain regions while also coinciding with low wind speeds, leading to moments when these renewable technologies fail to generate electricity.

      In 2024, “Several brief Dunkelflaute events, when wind and solar PV generation combined dropped to very low levels, caused drastic price spikes during several hours in the winter of 2024/2025 in Northern Europe,” the IEA’s Electricity 2025 report states.

      Addressing Supply Risks

      Despite the challenges these events pose to supply, the main threat lies in pricing rather than reliability, according to the Agency, as they necessitate the operation of dispatchable plants fueled by gas or coal.

      The Agency emphasizes that systems must prepare for an increase in such events. This necessitates enhancing the resilience of the grid, utilizing stabilization technologies, and diversifying energy sources, among other strategies.

      “Ensuring adequate dispatchable capacity and storage, in addition to flexibility options like demand-side response and interconnections, will be crucial for improving electricity security,” the IEA advises.

    • Global Electricity Storage Potential Exceeds Demand

      Global Electricity Storage Potential Exceeds Demand

      Researchers at the Australian National University have recently performed a study to figure out how many suitable sites there are for pumped storage power plants. They found that a staggering 86 trillion kilowatt hours could be stored thanks to all the potential power plants that could be created and added to the power grid when necessary.

      Understanding the Scale

      To give some context, global electricity production from every source, including coal and solar energy, is currently around 30 trillion kilowatt hours, or 30 petawatt hours. This means that even if global electricity demand were to double or triple due to electrifying transportation, boosting industrial production, or generating heat, 86 trillion kilowatt hours would still be enough.

      Mapping Opportunities

      The locations for these storage power plants have been gathered into an interactive atlas, where users can filter by size and type of pumped storage plant. This makes it easier to visualize where these plants could potentially be established.

      The research team also pointed out many benefits of pumped storage power plants. For instance, they do not harm or destroy existing river ecosystems, and they can be constructed in areas with considerable height differences. Compared to traditional dams, they require much less water, and their turbines face lower pollution levels because of reduced sediment.

      Utilizing Seawater

      Additionally, seawater could be used in numerous potential sites, eliminating the need for a second reservoir and practically negating water consumption. The expected lifespan of such plants ranges from 60 to 100 years.

      Cost-wise, the expenses differ widely depending on the region and type of pumped storage plants, but it’s estimated to be around $1 billion per gigawatt of capacity. This is not significantly higher than the costs associated with current wind and solar power facilities.

      There is one drawback: these facilities can’t generate electricity; they can only store it. However, they do this effectively, as energy can be kept for up to six months with an average efficiency of 80%.

      The Need for Other Energy Sources

      Thus, the electricity itself must come from alternative sources. The researchers primarily suggest wind and solar energy for this purpose. The slow expansion of these resources is linked to inconsistent production, insufficient government support, and the lack of storage solutions.

      In conclusion, it appears that appropriate electricity storage systems can be established in nearly any location, especially on the right scale, even though they still need to be built. Nonetheless, there remains a significant amount of work to be done before this becomes a reality. Currently, only a few pumped storage power plants have a capacity of 1 gigawatt.

    • Massive Natural Hydrogen Deposits Found: 200 Years of Energy

      Massive Natural Hydrogen Deposits Found: 200 Years of Energy

      When discussing hydrogen, the situation is very straightforward: these small molecules can even seep out of large steel tanks, and they are naturally found in the earth’s crust but are released directly into the air. This process occurs uniformly across the globe, making direct use of it impractical.

      New Findings on Natural Hydrogen

      Recent discoveries of significant natural hydrogen deposits in Mali, Oman, and Germany have led to a reevaluation of the presence of these concentrated, almost pure H2 reserves. A new study published in Science Advances reveals that prior beliefs regarding the capacity for natural hydrogen production have underestimated the actual reality significantly.

      Global Demand vs. Natural Supply

      Currently, the world needs about 500 million tons of hydrogen each year to eliminate fossil fuels completely. Earlier studies estimated that only 20 to 50 million tons are produced and escape into the atmosphere annually. However, if hydrogen can accumulate in appropriate underground reservoirs—an idea that is now gaining traction—the total global supply could be around 5.6 trillion tons. This quantity would allow us to live without fossil fuels for thousands of years.

      Researchers believe that a limited amount of this hydrogen is located in areas accessible with existing drilling technology. Given this, they estimate that the available hydrogen would last approximately 200 years.

      Future of Renewable Energy

      This provides ample time to develop renewable energy resources. Meanwhile, another type of fuel can be utilized that, while still being a fossil fuel, does not emit CO2 or other harmful byproducts during its use.

      The study highlights that this approach could temporarily address the hydrogen storage issue. The adaptable fuel can be extracted as needed while leaving the remainder in suitable geological formations.

      Nevertheless, it is important to acknowledge one more consideration: there is a significant margin of error in these calculations. The estimated supply ranges from 1 billion to 9 trillion tons, with the most likely figure being around 5.6 trillion tons. Even a fraction of that could lead to groundbreaking changes in energy production.
